Frequently Asked Questions

What's the best AI tool for taking meeting notes?

Notion AI can summarize meeting transcripts directly in your workspace. For dedicated meeting transcription, tools like Otter.ai and Fireflies work well and integrate with Notion and other productivity platforms.

How do AI productivity tools handle privacy?

Privacy varies by tool. Notion AI, ChatGPT Enterprise, and Claude Team all offer data processing agreements and opt-outs from training. For highly sensitive work, look for tools with explicit privacy guarantees and don't paste confidential data into free consumer tiers.

Can AI tools help with project management?

Yes — tools like Notion AI and ChatGPT can draft project plans, break down tasks, write status updates, and summarize project documents. They're best used alongside dedicated PM tools like Linear or Asana rather than replacing them.
